After reading a recent thread about subframe connectors I am interested in installing a set of the full length ones. I am wondering about how the install process is done. I assume the originals would just be unbolted and then the new ones would be bolted on and welded. What kind of place would you take a car to have this done? I am assuming the car has to be up on a rack of course and I am assuming that somehow the installer has to be sure the car is set up in a way to be 100% straight and level. Could someone describe the process for me and how long it takes?
